2. First go to adjustment section below and turn the tracking adjustment lever
In figure 1 and see if this amount of adjustment does not work. If not then
changing the position of the tracking cylinder is required. In figure 3 you need to
lengthen or shorten the length of the cylinder positon to move the idler roll more to
the left or right depending on which way the idler roll has to go to get the belt to
return and have even travel of the sanding belt.
Note. When doing this adjustment move the tracking lever to it center position of
its travel so you will have more adjustment later.
3. One last thing be sure the fork on the back miss track switch is not preventing the
idler roll from moving over. Could be the sanding belt is on the wrong side of the
fork and stopping the cylinder from pushing the idler over
Adjustment
Sanding Belt Tracking and Oscillation
The sanding belt should oscillate left and right
without a tendency to slide off the rollers. If the
sanding belt runs outside of the normal track, it
will contact a limit switch and the machine will
stop automatically.
The oscillation settings have been made at the
factory, but should be checked by the operator.
NOTE : When a new sanding belt is installed,
there may be a slight length tolerance between
the right and left sides of the sanding belt which
may result in incorrect tracking. If this occurs,
the oscillation timing can be set to compensate.
1. Turn off belt tension switch and center the
sanding belt , turn belt tension switch back on.
Now turn the Head Set-Up switch to the right,
oscillation adjustment is done while abrasive belt
is running. (see Figure 6 in manual )
